A 21-year-old man has been found guilty of aggravated assault for causing a head injury to his 20-day-old daughter that left her with permanent brain damage

A 21-year-old man has been convicted of aggravated assault for intentionally causing his 20-day-old daughter a severe head injury that has left her with developmental delays and brain damage.

Abiola Ojo Adamo, also known as Michael, shook his head slightly and hunched over in the prisoner’s box as Superior Court Justice Michael Dambrot read out his decision Friday morning.

Adamo “was a young father trapped in a domestic situation when he clearly still wanted to be playing the field,” Dambrot said.

On Nov. 16, 2012, he was left at their apartment near Jane St. and Wilson Ave. to look after the baby, Abike, while her mother Gurna Toussaint, 20, went to do her G1 driving test.

Toussaint was gone for four hours, much longer than he expected and Adamo had plans to meet another young woman later that day, Dambrot found.

Adamo became angry and frustrated with the crying baby and somehow applied blunt force to her head, Dambrot found.

He also forced a baby bottle into Abike’s mouth in an attempt to quiet her, tearing the membrane between her tongue and the bottom of her mouth, the judge ruled.

Adamo lied to police and to various other people in his life so often and with such little hesitation that Dambrot was “unable to believe anything he said on the witness stand.”

Adamo told police in three separate interviews that he was the only one home with his daughter during the timeframe doctors believe she received injuries to the head that could not have come from a fall.

However, earlier this week Adamo testified that Joshua Armah, the young man who rented the second bedroom in their apartment, was home that day and played with Abike alone for up to 45 minutes that day.

Dambrot found this to be a “late-breaking fabrication.”

It was “inconceivable” that, if Armah had been alone with Abike that morning, that Adamo did not mention it to the police in his first two interviews, or to Children’s Aid Services, Dambrot said.

It is “beyond comprehension” that he did not mention it to police after he was arrested on Jan. 18, 2012.

Dambrot found that Toussaint’s testimony that she heard Armah ask Adamo for Abike as she left that morning to be a “transparent lie,” clumsily executed in an attempt to shield Adamo from conviction and to reunite her family.

Dambrot found that while Armah was home that day, he had never shown much interest in Abike, would not have played with her, and would not attempt to feed her with a baby bottle.

In his decision, Dambrot also referenced a bizarre moment in Adamo’s testimony where he spent a few minutes expressing annoyance that Toussaint took Abike to the hospital on the night of Nov. 16 against his advice – despite the fact that her decision likely saved Abike’s life.
